Objective: Full quantification of dynamic PET data requires the knowledge of tracer concentration in the arterial plasma. However, its accurate measurement is challenging due to the presence of radiolabeled metabolites and measurement noise. Mathematical models are fitted to the plasma data for both radiometabolite correction and data denoising. However, the models used are generally not physiologically informed and not consistently ...

In order to improve the denoising performance in positron emission tomography (PET) images, various smoothing filters have been applied. Recent reports on PET denoising indicate that the signal-to-noise and contrast-to-noise ratios have been improved by sinogram-based pre-denoising. In this study, we propose a sinogram-based dynamic image guided filtering (SDIGF) algorithm for noise reduction. The proposed algorithm uses a normalized static ...

Monolithic crystals are considered as an alternative for complex segmented scintillator arrays in positron emission tomography systems. Monoliths provide high sensitivity, good timing, and energy resolution while being cheaper than highly segmented arrays. Furthermore, monoliths enable intrinsic depth of interaction capabilities and good spatial resolutions (SRs) mostly based on statistical calibrations. To widely translate monoliths into clinical applications, a time-efficient ...

Positron Emission Tomography (PET) data are inherently noisy due to low photon counts. To achieve an acceptable signal-to-noise ratio (SNR), Gaussian Filter (GF) with varying levels of full width half maximum (FWHM) accounting for the intrinsic resolutions of different scanners are employed at the expense of reduction in spatial resolution and hence accurate delineation and quantification of lesions. Edge preserving ...
